Characterizing the microbiological conditions in an environment where corrosion is occurring is an essential part of diagnosing the biotic and abiotic corrosion mechanism(s) responsible for the damage. Microbiological characterization often includes assessing the diversity, activity, numbers, and distribution of microorganisms in biofilms that are in contact with corroding and non-corroding surfaces. The use of DNA- and enzyme-based microbiological test methods by industry continues to grow each year as demonstrated by increasing numbers of service providers and field applicable technology platforms. Although there is promising research on genetic biomarkers for detecting microbiologically influenced corrosion (MIC), there is still no single test method that provides all of the information required for a clear MIC diagnosis. Experts and industry standards agree that multiple lines of evidence (MLOE) are still needed to diagnose MIC, including information about the chemical and physical conditions present, corrosion products and materials properties, asset design, and operational data. Recent industry standards and educational initiatives are helping to familiarize end users with the application of molecular microbiological methods and appropriate approaches for integrating, analyzing, and applying the test results.
